摘要

The 90-year old Clear Lake dam was modified for overtopping protection in 1996. The dam is a rockfill embankment, with a steel sheet-pile cut-off wall. Founded on landslide talus, the dam increased the storage in a natural lake created by the slide. The original outlet was a 20" riveted steel outlet, with a bifurcated section using two 16" conduits placed within a timber crib tunnel, and gates located under the crest of the dam. In conjunction with the armoring project, the outlet was renovated to provide control and guard gates in an upstream wet-well gate tower. When the reservoir was refilled, sink-holes developed over the connection between the new and old outlet conduits. As plans were being developed to repair the outlet, investigations revealed that the outlet was collapsed, and release flows apparently were being conveyed through the rockfill embankment itself. The subsequent repair design entailed soft ground tunneling under the dam, and grouting a PVC conduit within the tunnel.
